Quantum and atomic physics can often be an abstract and difficult subject for students to learn. Derived here is a simple model for helium and two-electron systems that may make some concepts, such as screening, easier for students to understand. We extend Bohr’s derivation, assuming a natural electron configuration, to explain some of the spectral lines of helium (He).

Surely, no budding scientist imagines him/herself as ever working in the legal field. Interestingly, though, both graduate school and law school overlap in at least one regard. Defending one’s stance with appropriate data in a compelling manner is a skill that everyone, scientist or lawyer-to-be, is forced to pick up along the way. This skill’s utility makes scientists attractive prospects for careers in intellectual property law.

Chemotherapy, hormone therapy, biological therapies including vaccines and antibodies, painkillers and other drug cocktails produce an array of unwanted side effects to an already ill person. Such side effects often make the disease feel as if it is dragging on longer and longer. This is a paradox. Packing an ailing body with poison and calling it treatment, all while harming the already pained and sick individual more.

An increasing amount of data suggest that women are disproportionately represented in STEM fields: science, technology, engineering, and math. According to the National Science Foundation’s 2015 report on Women, Minorities, and Persons with Disabilities in Science and Engineering, women comprise fewer than 20% of Bachelor’s degrees conferred in computer science and engineering. Additionally, many women in STEM fields report discrimination from colleagues and mentors alike.

A team of scientists, led by Jillian Banfield of the University of California - Berkeley, redesigned the Tree of Life on Monday after discovering thousands of new bacterial organisms over the last 15 years, according to a UC-Berkeley news release.
